This workshop constitutes a continuation of the OPENQMBP 2023, and it aims at to bring together scientists from different communities in the out-of-equilibrium physics of open many-body quantum systems. It has a particular regard for its applications to quantum information theory and quantum technologies.
Developments in quantum science and quantum engineering have indeed brought forth various platforms for quantum simulations of emergent collective many-body phenomena. Examples include ultracold trapped atoms and ions, superconducting circuits and atomic or solid-state quantum cavity-QED systems. A crucial feature of all these systems is their intrinsic non-equilibrium nature, where coherent quantum dynamics competes with dissipation arising from coupling to external environments due to unavoidable losses, dephasing and decoherence processes.
In the field of quantum computation the advent of noisy intermediate-scale quantum (NISQ) devices – quantum systems consisting of many qubits, over which experiments have imperfect control – is already beginning to revolutionise our understanding of quantum dynamics and quantum information science. While an ideal quantum computer is a closed unitarily-evolving system, any realistic implementation will have both controlled operations and unintended interactions with the external environment, leading to non-unitary, open-system dynamics.
Furthermore, open quantum systems are natural platforms to explore transport phenomena in interacting quantum many-body systems. This topic has seen a resurgence of interest with fundamental theoretical breakthroughs and experimental progress in realising transport settings with artificial quantum matter, beyond the conventional solid-state regime.
